Need to upgrade Phono section of Rogue Cronos mag


I enjoy the Musical nature of my Roque audio Cronos Magnum, having tried others still sounds great.
My issue is as good as it is overall the Phono section is rather lacking .. 

Thought of looking for a dedicated phono preamp but do not want to get into a major expense.
Bellari is as simple as it gets but not sure if it's a step up .. the Cronos has very little gain from the phono section  that's 1 st issue then the quality can only get better  .

When using line stage [ CD'S etc.] excellent results .
I end up using my Pharaoh int amp fro Vinyl  & Cronos for all other .  

I'd say i'd be comfortable spending under $ 1k  [ half - 500 would be nice ]

If you can find one, a Blue Circle BC27, although no one seems to part with ’em very often!

A Graham Slee Era V Gold or Croft RIAA (2 x 12AX7 tubes) are also in your budget.
Have you called the guys at Rogue? They might be able to help you. They're great people and they answer the phone. 
If turning up the volume is the issue just turn it up. IMO you should wait until you can make a significant improvement before upgrading
The Cronus Magnum 2's phono section was pretty good I thought. Which CM model at you using?
